I am 14 years old, I weight 150 pounds, I want to be ready for sophomore football in August. Are there any exercises that I can do from now until then so that I can be ready?

I have my diet covered, so I only need exercises. I am already doing cardio an hour a day, so muscle building is what I am mainly looking for.

I am a freshman, but I did not play football this year. I am about 5′ 9.5″- 5′ 10″, I weight about 140 lbs, I would like to know what I must work on to be a running back next year, like how much I should be able to bench, how fast of a mile time, or how tall I should be and how to improve on such things, also any helpful drills to do or something similar. Any help is appreciated, thank you.

I am a sophomore in high school and am thinking of joining the football team. I am 6′ 1″ and weigh about 190 lbs. I am not very fast but am pretty good at tackling (or so I think lol). I am probably the least likely person in our school to ever play football, but I like to surprise people. Please help, especially any high school football players!!
I think blocking would be best for me.
